"Trials happened between November 27th, 1930, and January 5th, 1931.
- Maximum speed:
- Good road: 35.2 kph.
- Dirt road, covered in packed snow: 30-35 kph.
- Off-road, covered in snow, in places up to 400 mm deep: 19-20 kph.
- Average speed:
- Asphalt or dirt roads, covered in packed snow: 27.6 kph.
- In a column of 3: 20.2 kph.
- Off road, covered in snow, up to 400 mm deep:
- One tank: 18 kph.
- Three tanks in a column: 12.5 kph.
- Range: Asphalt or dirt road covered in packed snow: 110-130 km.
- Capable of crossing five rows of two-strand barbed wire, forming a passage 3.5-5 meters wide.
- Shooting results: Shots were fired from the machine gun, using the optical sight, at a target 3*3 meters, at 250 meters, while moving off-road in the snow. It should be noted that shots from 18-20 kph are not indicative of the performance, due to insufficient training of the tank commander and platoon commander, as this is the first time there were shooting at a high speed. There was also no synchronization between the crew, the driver did not properly execute orders of the turret commanders. The shooting was also affected by temperature of -17 degrees.
- At 5-6 kph: out of 40 bullets fired, 32% hit.
- At 10-12 kph: out of 40 bullets fired, 30% hit.
- At 18-20 kph: out of 40 bullets fired, 12% hit.
- Conclusions:
- This type of tank stands out in its class for use in mechanized units.
- High mobility, maneuverability, agility, and other qualities are satisfactory for a light tank in mechanized units.
- These characteristics are accomplished by poor passive protection: armour.
- The configuration of the tank is accomplished by reducing convenience while servicing the motor.
- Shot accuracy while moving is notably high.
- The hull shape gives the enemy a small target.
- In the event of engine failure: torn gasket, torn exhaust valve, need of re-lubrication, etc. require the engine to be removed completely. In order to remove the engine, all armoured plates are removed from the inside of the tank."
